Methods and systems are provided for an exhaust gas treatment device. In one example, the exhaust gas treatment device comprises an electrochemical cell having a first electrode, a second electrode and an electrolyte provided between the first and second electrodes, wherein the electrochemical cell is configured to convert a first pollutant species, such as nitric oxide, within the exhaust gas to a second pollutant species, such as nitrogen dioxide, such that a concentration of the second pollutant species within the exhaust gases leaving the exhaust gas treatment device is increased relative to the exhaust gases entering the exhaust gas treatment device.

An exhaust passage includes a main passage and bypass passage, a catalyst, an exhaust control valve, and an HC adsorbent in the bypass passage. The exhaust control valve is controlled so that, when a temperature of the catalyst is higher than a predetermined sintering occurrence temperature, the quality of HC desorbed from the HC adsorbent is greater when the air-fuel ratio of the exhaust gas flowing through the upstream exhaust passage portion is a lean air-fuel ratio compared to when it is a stoichiometric air-fuel ratio or rich air-fuel ratio, or the quality of HC desorbed from the HC adsorbent is greater when the air-fuel ratio of the exhaust gas flowing through the upstream exhaust passage portion is a larger lean air-fuel ratio compared to when it is a smaller lean air-fuel ratio.

An exhaust gas control apparatus for an internal combustion engine for purifying exhaust gas discharged from an engine main body includes an exhaust gas control catalyst disposed in an exhaust gas passage of an internal combustion engine and capable of purifying a target component in the exhaust gas, an electrochemical reactor disposed in the exhaust gas passage on a downstream side in an exhaust flow direction of the exhaust gas control catalyst, and a control device for controlling energization of the electrochemical reactor. The electrochemical reactor is configured to purify the target component in the exhaust gas when energized. The control device controls the energization of the electrochemical reactor on the basis of an active parameter indicating an active state of the exhaust gas control catalyst and an air-fuel ratio parameter related to an air-fuel ratio of the inflow exhaust gas flowing into the electrochemical reactor.

A composition having an extract of seed of Emblica officinalis. Methods of preparing extract of seed of Emblica officinalis. An amla seed blend composition having various ratios of extracts of seeds of Emblica officinalis. Nutraceutical or pharmaceutical methods for decreasing the total cholesterol, decreasing triglyceride, decreasing blood glucose level, enhancing HDL-C levels, increasing the HDL-C level to total cholesterol ratio, lowering LDL-C levels, decreasing the CRP level, decreasing the intima media thickening, reducing hair fall in mammals especially human beings. The extract of seed of Emblica officinalis, or the amla seed blend composition is more effective compared to extracts prepared from fruits of Emblica officinalis.

An exhaust system that includes a catalytic converter, selective catalytic reduction system, a muffler and, for certain applications, a diesel particulate filter that each include at least one filter that has an electric heating element, a metallic coating and a plurality of metal rods extending therethrough. The combination of elements are configured to heat the internal housings of the exhaust system and disrupt the direction of flow of exhaust gases which contain harmful toxic gases and pollutants and aid in removing and/or reducing said toxic gases and pollutants.

A system and method for reduction of Nitrogen Oxide emissions from marine engines by converting Nitrogen Oxide into Nitrogen is disclosed. The modular reactive cyclic induction apparatus connects to the exhaust of a conventional diesel marine engine and uses air pressure and the sodium chloride in seawater to create a molecular reaction to break down Nitrogen Oxide into Nitrogen by use of an induction apparatus. The system can also include a loop for removing Carbon Dioxide through electrolysis, and removes other environmental pollutants as well, including for example Sulphur oxides, hydrocarbons, and particulate matter during the process.

A transfer module for transferring power to a non-thermal plasma generator includes a power cable; a first epoxy; a second epoxy; an interface between the first epoxy and the second epoxy; and a well; the power cable including a conductor for conducting electrical power and an insulation layer for surrounding a portion of the conductor; the first epoxy being located within the well to surround the insulation layer; the second epoxy being located within the well to surround the conductor located within the well; the second epoxy being located outside the well to surround the conductor located outside the well.

An exhaust tailpipe/emissions filter employs a reusable/replaceable insert and is configured to slide into and/or onto the exhaust tailpipe of the automobile to reduce air pollution.

An exhaust system is described comprising an array of a plurality of operably coupled fluid treatment apparatus for the treatment of a fluid substance. Each one of the plurality of fluid treatment apparatus comprises a reactor chamber defined by a perimeter wall; a fluid inlet adapted to provide fluid communication from an external supply of a fluid substance to be treated to said reactor chamber whereby said fluid substance passes into and through said reactor chamber; a fluid outlet adapted to provide a fluid communication from said reactor chamber whereby said fluid substance passes from said reactor chamber; at least one electromagnetic radiation (EMR) waveguide, having a waveguide input port and a waveguide output port, operably coupled within said reactor chamber and adapted to couple electromagnetic radiation of at least one predetermined wavelength to a fluid substance passing through said reactor chamber, wherein said perimeter wall of said reactor chamber is adapted to force said fluid substance received from said fluid inlet and passing through said reactor chamber into a continuous swirling flow towards said fluid outlet.
